The present invention relates to an improved colon irrigating syringe.

An object of the present invention is to provide an improved syringe arranged for insertion into the rectum and provided with a water supply conduit therethrough for conducting water to and from the colon in an improved manner so as to eliminate the possibility of the existence of abnormal pressures and to assure the free flow of matter loosened in the colon.

Another object of the present invention is to provide an improved syringe which has the above mentioned desirable features and which may be readily made in an inexpensive manner in accordance with present day mass production methods.

Still another object of the present invention is to provide an improved syringe substantially circular for easy insertion and removal and yet adapted to allow the free flow of matter loosened in the colon by water circulatin through the syringe.

The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. This invention itself, both as to its organization and manner of operation, together with further objects and advantages thereof, may be best understood by reference to the following description taken in connection with the accompanying drawings in which:

Figure 1 is a perspective view of an improved syringe embodying the present invention.

Figure 2 is a sectional view taken substantially on the line 22 of Figure 1.

Figure 3 is a, sectional view taken substantially on the line 3--3 of Figure 2.

Figure 4 is a view taken in the direction indicated by the arrows 4-4 in Figure 2.

An important feature of the present invention is the shape of the part l adapted for insertion into the rectum. This part is substantially cylindrical but at its end has a pair of segmental portions cut away or scalloped to provide a pair of side openings therein to allow the free fiow of solid matter loosened from the colon. The water is circulated in the direction indicated by the arrows 9.

The part I0 encompasses a water inlet tube 1 i which terminates at one end at the enlarged angularly ofiset tubular portion l2 adapted to receive a hose connected to a suitable supply of clean water and which terminates at the other end at the enlarged portion 13 which is in communication with the V-shaped ports l4, IS in the '2 rectangularly shaped plug member It. This plug member I6 is arcuate shaped at its forward face I? to allow easy insertion of the syringe. The particular shape of this plug or manifold member 16 is important.

The part [0 is hollow with the back end 20 thereof adapted to receive a hose for leading oif the water which is circulated through the colon and with the forward end thereof carrying the plu or manifold member l6 which is adjacent the pair of milled openings 2|, 22 in the cylindrical part 10.

It is noted that the plug or manifold member has substantially a rectangular cross section as shown in Figures 1 and 4 with the longer cross sectional dimension substantially equal to the diameter of the tubular part I0 and with the shorter cross section dimension substantially less than the diameter of the part II]. This is an important feature since when the syringe is inserted in position there is provided an open space adjacent the side faces 30, 3| past which the dislodged matter may fiow into the corresponding exit openings 2|, 22 without causing water pressure to build up in the colon.

Thus, water from the supply tube I 2 is directed out of the forward ports l4, l5, flows and circulates through the colon carrying with it matter dislodged thereby, and in its return, the water with the matter carried in it flows past the faces 30, 3! into the correspondin exit openings 2|, 22 which are communicated with the hollow cylindrical tube 28 from where it may be lead off as waste.

Of importance is the fact that the flow of water with the dislodged matter therein is not impeded clue to the special construction of the forward end of the syringe thereby allowing prolonged circulation of the water through the colon without a great amount of care and attendance.

The syringe may have an annular flange 35 thereon to limit or to provide a measure of the amount of degree to which the syringe is inserted.

The improved structure makes it possible to easily clean the syringe because of the large main central passageway therethrough which gives easy access to the inside of the main tube.

While the particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from this invention in its broader aspects and, therefore, the aim in the appended claims is to cover all such changes and modifica- 3 tions as fall within the true spirit and scope of this invention.

I claim:

1. A colon irrigating syringe comprising a main cylindrical tube adapted for insertion into the rectum with the forward end of said tube scalloped to provide two side openings in said tube; a rectangular manifold at the forward end of said tube contiguous to said openings, the larger cross sectional dimension of said rectangular manifold being substantially equal to the diameter of said cylindrical tube; and an inlet tube extending through said tube in communication with said manifold.

2. A colon irrigating syringe comprising a main cylindrical tube having, at its forward end, diametrically opposite wall portions thereof removed to provide side openings to said tubes, and to provide said forward end with a substantially rectangular cross section; a manifold member, of cross section substantially equal to that of said forward end, at said forward end contiguous to said openings; and a water inlet tube confined within said cylindrical tube in communication with said manifold member.
